Choose this motor when you need a compact, high-torque unit for refined race setups and controlled acceleration.

Is this motor suited for off-road buggies?

It is optimised for on-road high speed use. Off-road applications may demand different torque curves and shaft protections, so review your chassis needs first.

Can I run it on common LiPo packs?

Yes, but ensure the cell count and ESC limits match motor RPM and current draw. Monitor temperature during initial runs to confirm your setup.

What maintenance does it need?

Regularly check bearings, clean vents, and inspect soldered joints. Replace worn brushes or bearings as needed to keep performance consistent.

Does it require a specific ESC setting?

Tune your ESC timing and throttle curves to match your drivetrain and track. Start with conservative timing to keep temperatures down, then adjust for lap times.
